What it is

The O-RING 9.0X4.0X2.5 EPDM X10 is an EPDM sealing O-ring supplied in a pack of ten for Worcester Bosch appliances. It is listed for Worcester HIU Spares. The O-ring seals a joint or connection within the appliance to prevent leaks.

Signs this part needs replacing

  • Visible cracks, splits or flattening on the O-ring
  • The O-ring has hardened and no longer seals flexibly
  • Weeping or dripping at the joint where the O-ring is fitted
  • Scale, debris or corrosion on the sealing surfaces
  • Repeated loss of pressure or water at the connection

Before you order

  • Confirm the removed O-ring matches the stated 9.0 x 4.0 x 2.5 size
  • Confirm EPDM material is suitable for the application
  • Check the appliance is covered by Worcester HIU Spares fitment
  • Confirm the required quantity; the pack contains X10
